6 Claims.

This invention relates to consumer type containers and refers particularly to containers made of fiber or paper board and provided with a reclosable cover.

In the production of consumer type containers of fiber or paper board the problem of providing adequate rigidity for the mouth or open top of the container and at the same time having the opening unrestricted without sacricing neat appearance and entailing high production `costs has perplexed the industry for quite some time. In Patent No. 2,398,404, issued to the applicant April 16, 1946, consumer type containers are illustrated in which the open upper end of the container body has increased strength and rigidity afforded by a simple inexpensive shouldered construction but in this case the reinforcement either partially obstructs the opening or the construction is such that the incorporation of a reclosable cover is impractical and too costly for many products which require a full sized opening as, for instance, `soda crackers and cigarettes.

One of the purposes of this invention, there-l fore, is to provide an improved container of the character described in which ample strength and rigidity are provided for the mouth of the container by a novel, inexpensive neck construction with which the reclosable cover has telescoping engagement.

Another purpose and object of this invention is to provide a container of the character described which is so designed and constructed that both its end closures, that is, its bottom and its cover, may be made or formed over an internal support.

Another object of this invention is to so con-l struct the body and cover of the container that the flanges on the cover Which flt over the neck are formed simultaneously Withthe body blank so that the cover flanges will be absolutely flush with the front and side walls of the container.

Another object of this invention is to provide a container of the conventional one piece carton type with a neck at its open top and a reclosable hinged cover adapted to have telescoping engagement with the neck.

With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement oi parts substantially as hereinafter described and more particularly deiined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

The accompanying drawings illustrate several complete examples of the physical embodiments of the invention constructed according to the best modes so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective View of a container embodying this invention, said view showing the cover of the container open;

Figure 2 is a perspective View of the container shown in Figure 1 but With the cover closed and partially sealed;

Figure 3 is an enlarged detail sectional view, in perspective, through Figure 1 on the plane of the line 3 3; y

Figure 4 is a perspective view of the unit or piece from which the back, bottom and cover of the container shown in Figure 1 are formed;

Figure 5 is a perspective view of the formed-up piece or unit comprising the front and side walls of said container;

Figure 6 is a plan view of the blank which prdduces the back, bottom and cover forming unit shown in Figure 4;

Figure 7 is a plan view of the blank which produces the front and side wall unit shown in Figure 5;

Figure 8 is a perspective View with parts broken away and in section, illustrating another modication of this invention;

Figure 9 is a perspective view showing the two pieces from which the back, bottom and cover flanges of the container shown in Figure 'Sare formed; and

Figure 10 is a plan view of the so-called body blank for the container shown in Figure 8 and illustrating particularly the manner in which the cover anges are formed concomitantly with the formation of the body blank.

Referring now particularly to the accompanying drawings in which like numerals indicate like parts throughout the several views, the numeral 5 designates generally the body ofV a consumer type container of the type With which this invention deals and which is characterized by the fact that it has a full opening top reinforced by a neck 6 and closed by a hinged cover 1.

In that embodiment of the invention shown in Figures l through '7, inclusive, the container is made from two separate pieces or units (Figures 4 and 5) the one shown in Figure 4 providing the back wall 8 of the container, the bottom Wall 9 and the hinged cover 1, While the other unit shown in Figure 5 provides the front Wall l0 and side walls ll.

As shown in Figure 'I the unit or piece providing the front and side walls is formed from a blank which is vertically scored as at I2 to define the three panels which provide the front and side walls, and also Vertical glue flaps I3 which extend for the full height of the blank. Across its bottom the blank is scored horizontally as at I4 to define bottom attaching flanges I5 on the front and side walls and also on the glue flaps I3, the strip providing these iianges being preferably diagonally scored as at I5 to facilitate the corner folds necessary to enable the anges I5 to be turned in without requiring cutting the same at the corners.

Across its upper portion the blank shown in Figure 7 has three parallel spaced horizontal score lines I'I, I8 and I9. These score lines define three parallel adjacent strips 28, 2i and 22 which are folded upon themselves to produce the neck 6. To obviate bunching of the material at the corners the strip 2S is cut out as at 23 adjacent to each corner defining score line I2.

y As clearly shown in Figure the strips'ZIl, 2I land 22 which are of progressively greater widths are so disposed with respect to each other that the neck formed thereby is disposed inwardly of but parallel to the outer walls of the container. Thus, the strip is bent down over the inner face of the front and side wall panels and the glue aps I3, to all of which it may be adhered, if desired, and then the intermediate strip 2a is bent upwardly on the score line I8 to extend above the top of the body. Next, the third and final strip 22 is folded down over the inside face of the intermediate strip 2I and because of its greater width extends beyond or below the junction of the rst and second strips deiined by the score line I8 to overlie and be adhered to the adjacent inner faces of `the front and side wall panels and the yglue flaps I3.

Since the strips 20, 2l and 22 extend across the glue aps I3l as Well'as the front-and side wall panels the neck 6 formed thereby continues unbrokenly around all four corners of the container and extends across all but the back wall thereof.

The blankshown in Figure 6 from which the back and bottom walls and cover are formed is scored transversely or horizontally as at 24 vand 25 to dene the top and bottom edges of the back wall and provide the hinge about which -the cover 'I swings, In addition this blank has two other transverse or horizontal scores 2B and 21 and vertical scores 28 in line withand forming' extensions of the side edges of the back wall forming panel. These score lines..2$, 21 and 28 vdene the top wall`29 of the cover and flange portions 3G, SI and 32 respectively at the back, front and side edges of the top wall.

In forming up the piece or. unit shown in Figuref?t from the blank just described, the flanges 3Il, 3| and 32 are bent perpendicularly tothe top wall. portion 29 andsecure'd together by the tongues 33 which in effect form extensions ofthe flanges and 3! and which overlap and are adhered to the side flanges 32.

The two pieces or units are, of course, secured together by means of the glue fia-ps I3 which are adhered to the inner marginal edgesof the back wall 8. After the two units or pieces are secured together, the resulting tube is slipped over an `internal supporting mandrel 34 as shown in Figurell to support the cover 'I as it is formed, i. e. during the time. the tongues 33 are adhered to the adjacent side iianges 32. The container is then stripped off the supporting mandrel and reapplied upside down as shown in Figure 12. This permits the bottom wall of the container to be likewise formed over an internal support 'and which, as will be readily apparent, is effected by adhering the bottom forming flap 9 to the inturned flanges I5.

This completes the container which then may be filled with the commodity for which it is designed and after it is full the cover is closed and sealed shut by applying a pressure sensitive` strip 35 around the upper portion of the container as shown in Figure 2, or any other suitable manner of securing the cover closed may bc employed.

In any event, upon removal of the sealing strip 35 or its equivalent the cover may be opened and reclosed at will.

Another embodiment of the inventoin is illustrated in Figures 8, 9 and l0, In this case the two piece construction just described is employed but the cover flanges are provided by a separate strip or piece 55 which is conveniently produced as part of the blank (shown in Figure 10) from which the front and side walls of thecontainer are formed. In other words, the strip 5-5 before being severed from the body forming blank has its corner forming scores 55 formed therein at the same time the corner scores I2 are formed. At the same time the strip 55 is longitudinally scored as at 51 to enable the same to be bent to right angular shape in cross section and is diagonally scored as at 58 to allow folding over its horizontal flanges in the formation of the cover.

The manner in which the strip 55 is formed up and attached to the cover forming fiap 29 is deemed obvious from the drawings, especially from Figures 8 and 9; and since the strip 55 is initially part of the body forming blank and is scored concomitantly therewith the cover will t perfectly and its flanges will be absolutely flush with the front and side walls of the container. The neck 6' in this embodiment of the invention is produced in the same manner as that described in connection withFigures 1 to 7, in-

clusive.

vFrom the foregoing description takenin connectionwith the accompanying drawings it will be readily apparent to those skilled in this art that this invention provides a consumer type container having many advantages over consumer type containers heretofore available, especially in view of the fact that the invention provides a full opening container which may have both top and bottom ends formed over an internal support and upon being opened by the consumer still has a convenient reclosable cover.
